A web service is a software component that may make services available over the internet. Web services may use a standardized extensible markup language (XML) messaging system that is used to encode communications to a web service. Web services provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks. Web Services are self-contained, modular, distributed, dynamic applications. Web services typically provide application programming interfaces (API) or a defined set of hypertext transfer protocol (HTTP) request messages along with a definition of the structure of response messages that are accessed and executed on a remote system hosting the requested services. Web services may manipulate extensible markup language (XML) representations of web resources provided by web servers. Data elements may be provided by web services and may be described by schema that provide specifications for the use and representation of the data elements in various applications. Web services may employ reusable application components and may promote exchange of data between different applications and different computing platforms. Web services may help to solve interoperability problems by giving different applications various means to link their data.
